Struct Ipv6Hdr 

#[repr(C)]
pub struct Ipv6Hdr {
    pub vcf: [u8; 4],
    pub payload_len: [u8; 2],
    pub next_hdr: u8,
    pub hop_limit: u8,
    pub src_addr: [u8; 16],
    pub dst_addr: [u8; 16],
}

IPv6 header, which is present after the Ethernet header.

Fields

vcf: [u8; 4]

First 4 bytes containing Version (4 bits), Traffic Class (8 bits), and Flow Label (20 bits)

payload_len: [u8; 2]

Payload length (excluding the IPv6 header)

next_hdr: u8

Next header protocol

hop_limit: u8

Hop limit (similar to TTL in IPv4)

src_addr: [u8; 16]

Source IPv6 address (16 bytes)

dst_addr: [u8; 16]

Destination IPv6 address (16 bytes)
